Alarm type
under voltage
: occurs
when the voltage is below
the standard value.
over voltage :
occurs when
the voltage is above
standard value.
main circuit error :
occurs
when the IPM malfunctions.
encoder signal error :
occurs when encoder signal
malfunctions.
encoder receive
initialization error :
occurs
when encoder is not initialized
over speed :
occurs when
the motor speed exceeds the
maximum running count.
over load :
occurs when the
over load status continuous for
a long time exceeding
standard time.
CPU error :
occurs when
the CPU malfunctions
there is fault with the board.
parameter error :
occurs when
the set parameter is not within
the range.
excessive position deviation :
occurs during position control
when the remaining pulse
exceeds the fixed value
parameter 19.
over current flow :
occurs if
the over current flows
the motor.
encoder battery error :
occurs when the backup
battery of the encoder
discharged or disconnected.

Corrective actions
- check if the input power is low.
- check if the motor power cable is open.
- check if the input power is high.
- check if the operation frequency is above
the
the standard value.
- check if regenerative resistor is damaged.
- check if the heat protection board is over
100 degrees celsius.
- check if the operation frequency is above
the standard value.
- check if the encoder connection is correctly
assembled.
- check if the encoder line is cut
data
- Drive turns the power off and then turns it
on 3 second later
- check if the encoder cable is missing or if it
correctly assembled.
- check if there is connection error in the
motor power cable.
the
- check if the parameter is set correctly.
or - check if the parameter is set correctly.
- check if the parameter is set correctly.
- check if the value of parameter 18 is set
too low.
of
- check if the accel/decel parameter is set on
too low value.
into
- check if the insulation resistor of the motor
is correctly displayed.
- change the battery.
